Tractor Hook-Up
Refer to Figure 1-1:
!
DANGER
Tractor hook-up to equipment is dangerous and can result in
serious injury or death. Do not allow anyone to stand between
the Powered Rake and tractor during hook-up operations. Do
not operate the hydraulic 3-point lift controls while someone
is directly behind the tractor or near the Powered Rake.
Depending upon model of rake, a 3-Point Category I or
Category II hitch is required. The lower 3-Point arms of
the 3-Point hitch must be stabilized to prevent side-to-
side movement. Most tractors have sway blocks or
adjustable chains for this purpose.
Prepare as follows:
1.
Determine your tractor’s hitch category.
a. A Category I tractor will have a 7/8” dia. hole in
the lower hitch links and a 3/4” dia. hole in the top
link.
b. A Category II tractor will have a 1 1/8” dia. hole in
the lower hitch links and a 1” dia hole in the top
link.
NOTE: Front tractor weights and/or ballast to tires
may be required to offset weight of unit. Consult your
tractor manual for details to install ballast weights.
2.
Slowly back the tractor up to the Powered Rake and
use the tractor’s 3-point hydraulic control to align the
lower hitch link holes with the clevis lug holes on the
Powered Rake.
3.
Engage tractor park brake, shut tractor engine off
and remove key before dismounting from tractor.
4.
With the tractor’s lower hitch arms aligned and
positioned in the clevises, attach lower arms to the
clevises with hitch pins and secure with linchpins.
5.
Connect top center link to the upper pivot hitch using
customer supplied clevis pin and linchpin.
6.
Stow jack stands in the raised position.
7.
Return to the tractor and slowly operate the tractor's
3-Point hydraulic control up and down to check for
clearance between tires, frame, drawbar, etc. Move
or remove drawbar if it interferes with the Powered
Rake.
8.
Manually adjust one of the two lower lift arms up or
down to level the Powered Rake from left to right.
9.
Manually adjust length of the top-link to level the
Powered Rake from front to rear.
10. Ensure that the lower arms are blocked to prevent
excessive side movement.
11. Adjust tractor's lower lift arms to level the Powered
Rake from left to right. Adjust top-link to level the
Powered Rake from front to rear. A final adjustment
will be made later.
